R. patient (Pequizeiro-GO) were incubated with different concentrations of a Ivermectin solution (50, 100, 150, 200 e 250 micrograms). The results demonstrated that any one concentration of the drug was efficient in prevent the larval development. However, after embryogeny a destruction process was observed with the larva within the eggs where there was elimination of an amorphous mass from the embryonic eggs.
